BACKGROUND: Sufficient tuberosity fixation in proximal humeral fractures treated with shoulder arthroplasty is essential to gain a good clinical outcome. This biomechanical study evaluated the strength of the reattached tuberosities in reverse total shoulder arthroplasty fixed with cables or with sutures in a cerclage-like technique. Considering the mechanical advantages of flexible titanium alloy cables compared with conventional sutures for cerclage-like fixations, we hypothesized that titanium alloy cables would achieve higher fixation strengths of the tuberosities compared with heavy nonabsorbable sutures...

We report a case of a 29-year-old man who presented with a distal humeral shaft fracture sustained by blunt trauma. Physical examination and nerve conduction study were consistent with injury to the median and radial nerves proximal to the elbow. The patient underwent open reduction and internal fixation of the humeral shaft fracture with neurolysis of the median and radial nerves. Repeat electromyography at 6 months postoperatively showed recruitment of motor units in all muscles sampled, in keeping with clinical improvement...

A non-union, especially atrophic non-unions, is a permanent failure of healing following a fracture and can be difficult to treat. Approximately 5-10% of fractures will result in a non-union during the healing process. non-unions can be classified into two types: atrophic non-union which is often due to impaired bone healing with a potential biological mechanism, and hypertrophic non-union which is due to inadequate fixation after fracture. Genetic variations also play an important role in the fracture healing response...

BACKGROUND: Distal humerus physeal separations are rare pediatric elbow fractures that are often misdiagnosed and difficult to treat. Adequate reduction is often technically challenging and up to 71% of children develop postoperative cubitus varus. We propose using the medial and lateral humeral lines as an adjunct to elbow arthrography in order to guide intraoperative fixation of distal humerus physeal separations to reduce the incidence of postoperative cubitus varus. METHODS: From 2009 to 2014, all pediatric patients under the age of 3 diagnosed with a distal humerus physeal separation and treated surgically at our institution were included for analysis...

BACKGROUND: This study regards a volumetric analysis of proximal humeral fractures. The main purpose was to investigate the head displacement in relation to the shaft and its link to volume reductions ("bone loss") of the anatomic segments interposed between the head and the shaft: the tuberosities and the calcar. We call this area "control volume." METHODS: In 20 fractures, we used 3-dimensional virtual reconstruction to create a reference system that divides geometrically the control volume and allows the evaluation of displacement angles of the humeral head...

BACKGROUND: Open reduction and internal fixation of proximal humerus fractures can be difficult to achieve adequate, complication free results due to osteopenia of the proximal humerus and unstable fracture patterns. This study aimed to compare the biomechanical properties of a novel hybrid fixed angle blade plate (Fx plate) with an established fixed angle locking plate (PHILOS plate). METHODS: A two-part fracture was simulated in synthetic composite humeri by creating a transverse osteotomy and 10 mm fracture gap at the surgical neck...

OBJECTIVES: Long head of the biceps tendon (LHB) is an obstacle to closed reduction in two-part fracture of the humeral surgical neck if the distal humeral shaft is displaced into the axilla in anteroposterior X-ray examination. METHODS AND MATERIAL: Among 36 proximal humeral fractures, 10 two-part humeral surgical neck fractures which were displaced into the axilla in anteroposterior X-ray views and classified as 11-A3.2 were included in this study. In all of these fractures, closed reduction attempts were unsuccessful...

Background: Fractures of the proximal part of the humerus represent almost 4-5% of all fractures. The rate of non union is estimated to be 1.1 to 10%. Non union, displacement, and fixation failure can be hazardous complications for these injuries. The purpose of our study was to evaluate the outcomes of plate and bone strut allograft with bone chips grafting augmentation in the management of proximal humeral aseptic non union. Methods: We treated 16 aseptic non union proximal humeral fractures by the medial humeral shaft bone strut allograft and lateral plate and screws with bone chips grafting...

Background: Non-union humeral shaft fractures are seen frequently in clinical practice at about 2-10% in conservative management and 30% in surgically operated patients. Osteosynthesis using dynamic compression plate (DCP), intramedullary nailing, locking compression plate (LCP), Ilizarov technique along with bone grafting have been reported previously. In cases of prior failed plate-screw osteosynthesis the resultant osteopenia, cortical defect, bone loss, scalloping around screws and metallosis, make the management of non-union more complicated...

Arm wrestling places significant torque on the humeral shaft. A spiral distal humeral shaft fracture is an unusual but significant injury that can result. Of 93 patients who presented between 2009 and 2017 with closed humeral shaft fractures that were managed nonoperatively, 9 sustained the fractures while arm wrestling. Outcomes were compared with those of all other patients with nonoperatively managed humeral shaft fractures sustained through other mechanisms. The Student's t test was used to compare cohorts...

The intention of the current article is to review the epidemiology with related socioeconomic costs, pathophysiology, and treatment options for diaphyseal long bone delayed unions and nonunions. Diaphyseal nonunions in the tibia and in the femur are estimated to occur 4.6-8% after modern intramedullary nailing of closed fractures with an even much higher risk in open fractures. There is a high socioeconomic burden for long bone nonunions mainly driven by indirect costs, such as productivity losses due to long treatment duration...

Valgus-impacted proximal humerus fracture is a classic but rare entity in shoulder traumatology. Surgical treatment is controversial, with increasing use of minimally invasive techniques. Our technique uses a minimally invasive approach under fluoroscopic control. Raising the humeral head to reduce the valgus enables spontaneous and well-positioned reduction of the tuberosities and screw fixation between the greater tuberosity and the humeral shaft. Indications comprise valgus-impacted fracture without comminution of the medial epiphyseal-metaphyseal hinge or greater tuberosity; the rotator cuff contributes to reduction and must be intact...

Introduction: Humerus non-union is a challenging situation for the surgeon and devastating and morbid situation for the patient. Surgical approach to the humerus is demanding because of the complex neurovascular anatomy and especially when previous surgeries have been attempted. Case Report: We report a case of a young adult male who sustained a compound fracture of humerus shaft treated with intramedullary nailing followed by subsequent bone grafting and eventually landed up in non-union and was treated at our center by locking compression plate application with nail in situ with iliac crest autogenous bone graft followed by shoulder spica application...
